Shares of STMicroelectronics rallied 11% Tuesday after management unveiled significantly higher revenue expectations for its data-center segment, powered by robust demand from AI infrastructure buildouts.
The Geneva-based semiconductor company now projects approximately $1 billion in data-center revenue for 2026. This represents a substantial increase from its earlier forecast of “nicely above $500 million.” Looking ahead to 2027, management anticipates this revenue stream will double on a year-over-year basis — surpassing previous guidance calling for “well above $1 billion.”
STM was changing hands near €62.82 during the most recent valuation assessment, representing a staggering 168% gain year-to-date as of early June 2026.
The automotive chip segment, historically a core revenue driver for STMicroelectronics, has experienced weakness for more than twelve months. In response, the company has strategically shifted focus toward power semiconductor solutions and optical connectivity products serving data centers — both critical components of the expanding AI hardware ecosystem.
STMicroelectronics has supplied semiconductors for SpaceX satellite systems since 2015 and maintains a commanding 90% share in this specialized market. With SpaceX’s anticipated public offering expected this month, this strategic partnership has captured heightened investor interest.
The semiconductor maker is also exploring preliminary opportunities around orbital data centers — computing facilities positioned in space. Remi El-Ouazzane, who leads this business unit at STMicroelectronics, characterized it as “something that we are very much involved with but have not been able to scope properly yet.”
This represents an intriguing long-term opportunity, though the company has not yet provided specific revenue projections for this initiative.
The broader analog semiconductor sector experienced gains alongside STMicroelectronics Tuesday. ON Semiconductor climbed 5.6%, Texas Instruments advanced 2.5%, and Infineon Technologies rose 5.9% during U.S. market hours.
Following such a dramatic appreciation, certain market observers are questioning whether the stock has outpaced its underlying business fundamentals.
Simply Wall St’s discounted cash flow analysis values STMicroelectronics at €45.32 per share intrinsically — indicating the current price of €62.82 potentially reflects a 38.6% premium to this calculated estimate.
The research provider assigns STMicroelectronics a valuation rating of merely 2 out of 6, positioning it in overvalued territory according to their analytical framework.
From a price-to-sales perspective, the assessment proves more nuanced. STM commands a P/S multiple of 5.20x, exceeding the semiconductor sector median of 4.88x while remaining below the specific peer group average of 6.34x. Simply Wall St’s proprietary “Fair Ratio” calculation for the stock stands at 11.87x — which would paradoxically suggest undervaluation using that particular methodology.
Trailing twelve-month free cash flow currently registers in negative territory at approximately -$702 million, though analyst projections anticipate a reversal to roughly $967 million during 2026, expanding further to $3.47 billion by 2030.
The 6.6% appreciation over the preceding seven trading days and 28.1% gain across the past thirty days demonstrate momentum continues building heading into the summer months.
